Answer:
B. Cross-train agents on both product lines
D. Implement a customer self-service portal
Explanation:
Cross-training is a way of teaching employees different aspects of the job so that they can have a measure of flexibility in the discharge of duties. Managers find this approach to be effective as they believe it saves cost and maximizes the usefulness of employees. It also helps to serve and satisfy a wider range of customers.
So for Universal Containers seeking to optimize cost without compromising customer satisfaction while managing two customer service contact centers, an effective way of dealing with the large call volumes is cross-training agents on both product lines so that they can attend to a wider range of customers. Cross-training agents on both product lines would make them more knowledgeable of the services being offered and this would minimize the need to transfer calls as all agents can provide information on the various products.
Implementing a customer self-service portal would also reduce the workload on the customer service agents as customers can access the information they need on their own.

Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
Answer: Provided in the explanation section
Explanation:
The Question says;
Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
The Answer (Explanation):
XOR, exclusive OR only gives 1 when both the bits are different.
So, if we want to have all 0s, and the for input only 10000001, then we have only one operation which satisfies this condition - XOR 10000001. AND
with 00000000 would also give 0,
but it would give 0 with all the inputs, not just 10000001.

Consider a load-balancing algorithm that ensures that each queue has approximately the same number of threads, independent of priority. How effectively would a priority-based scheduling algorithm handle this situation if one run queue had all high-priority threads and a second queue had all low-priority threads
Answer and Explanation:
Consider giving greater priority to both the queue contains the national priority comment section as well as, therefore, first method the thread throughout this queue.If the item from either the major priority queue becomes decoupled, if the balancing between some of the number of comments in some of these two queues becomes disrupted, instead decouple one thread from either the queue comprising the low-value thread as well as position that one in the queue with the highest - priority loop to match the number of connections in such 2 queues.Whenever a new thread arrives with some kind of proper description, a friendly interface could've been introduced to just the queue contains fewer threads to achieve stability.Therefore, the load-balancing requirements for keeping about the same number of threads would be retained and the meaningful matter of top priority thread would also be retained.
Based on the information given, it is important to give higher priority to the queue that contains the high priority thread.
Also, once an element from the high priority queue is dequeued, then dequeue one thread from the queue containing low priority thread and this will be enqueued into the queue having high priority thread in order to balance the number of threads.
Since the priority queue automatically adjusts the thread, hence the removal of the thread from one priority queue to another is not a problem.

Write a C++ program to find if a given array of integers is sorted in a descending order. The program should print "SORTED" if the array is sorted in a descending order and "UNSORTED" otherwise. Keep in mind that the program should print "SORTED" or "UNSORTED" only once.
Answer:
The cpp program for the given scenario is as follows.
#include <iostream>
#include <iterator>
using namespace std;
int main()
{
//boolean variable declared and initialized
bool sorted=true;
//integer array declared and initialized
int arr[] = {1, 2, 3, 4, 5};
//integer variables declared and initialized to length of the array, arr
int len = std::end(arr) - std::begin(arr);
//array tested for being sorted
for(int idx=0; idx<len-1; idx++)
{
if(arr[idx] < arr[idx+1])
{
sorted=false;
break;
}
}
//message displayed
if(sorted == false)
cout<< "UNSORTED" <<endl;
else
cout<< "UNSORTED" <<endl;
return 0;
}
OUTPUT
UNSORTED
Explanation:
1. An integer array, arr, is declared and initialized as shown.
int arr[] = {1, 2, 3, 4, 5};
2. An integer variable, len, is declared and initialized to the size of the array created above.
int len = std::end(arr) - std::begin(arr);
3. A Boolean variable, sorted, is declared and initialized to true.
bool sorted=true;
4. All the variables and array are declared inside main().
5. Inside for loop, the array, arr, is tested for being sorted or unsorted. The for loop executes over an integer variable, idx, which ranges from 0 till the length of the array, arr.
6. The array is assumed to be sorted if all the elements of the array are in descending order.
7. If the elements of the array are in ascending order, the Boolean variable, sorted, is assigned the value false and for loop is exited using break keyword. The testing is done using if statement.
8. Based on the value of the Boolean variable, sorted, a message is displayed to the user.
9. The program can be tested for any size of the array and for any order of the elements, ascending or descending. The program can also be tested for array of other numeric data type including float and double.
10. All the code is written inside the main().
11. The length of the array is found using begin() and end() methods as shown previously. For this, the iterator header file is included in the program.

Add two more statements to main() to test inputs 3 and -1. Use print statements similar to the existing one (don't use assert)
import java.util.Scanner;
public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
/* Your solution goes here */
System.out.println("Testing completed");
return;
}
}
__________
Answer:
import java.util.Scanner;
public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
System.out.println("3, expecting 27, got: " + cubeNum(3));
System.out.println("-1, expecting -1, got: " + cubeNum(-1));
System.out.println("Testing completed");
return;
}
}
Explanation:
Added statements are highlighted.
Since the cubeNum function calculates the cube of the given number and we are asked to write two statements to test inputs 3 and -1, pass the parameters 3 and -1 to the function called cubeNum and print the results using print statements

There are 7 rows and each row has up to 7 characters. The pattern is also symmetrical which makes it easier. Before writing any code, let's figure out how we are going to determine the correct amount of spaces we need to print. There are a lot of ways to do this, but I'll just show one. Let's call the 4th row y=0. Above that we have row 3 which would be y=-1, and below is row 5 which is y=1. With 7 rows, we have y=-3 through y=3. The absolute value of the y value is how many spaces we need.
To determine the number of stars, we just double the number of spaces, then subtract this number from 7. This is because we can imagine that the same amount of spaces that are printed in front of the stars are also after the stars. We don't actually have to print the second set of spaces since it is just white space, but the maximum number of characters in a row is 7, and this formula will always make sure we have 7.
I hope this helps. If you need help understanding any part of the code, jsut let me know.

The main() module in the starter code below takes integar inputs separated by commas from the user and stores them in a list. Then, it allows the user to manipulate the list using 3 functions:
mutate_list() takes 3 parameters -- a list, index number, and a value -- and inserts the value in the position specified by the index number in the list.
remove_index() takes 2 parameters -- a list and an index number -- and remove the element at the position number indicated by index. It also prints the total number of elements in the list before and after removing the character in this fashion:"Total elements in list = 11
Total elements in list = 10"
reverse_list() takes 1 parameter -- a list -- and returns the list reversed.
Examples:
Example 1:
Enter values in list separated by commas: 1,2,4,63,6,4,22,53,76
[1, 2, 4, 63, 6, 4, 22, 53, 76]

Consider the following concurrent tasks, in which each assignment statement executes atomically. Within a task, the statements occur in order. Initially, the shared variables x and y are set to 0.
Task 1 Task 2
x = 1 y = 1
a = y b = x
At the end of the concurrent tasks, the values ofa andb are examined. Which of the following must be true?
I. ( a == 0 ) ( b == 1 )
II. ( b == 0 ) ( a == 1 )
III. ( a == 1 ) ( b == 1 )
(A) I only
(B) II only
(C) III only
(D) I and II only
(E) I, II, and III
Answer:
(D) I and II only
Explanation:
Concurrent tasks is when there is more than one task to be performed but the order of the task is not determined. The tasks occur asynchronously which means multiple processors occur execute input instruction simultaneously. When x =1 and y = 1, the concurrent task will be performed and the a will be zero or either 1.
a. A programmer wrote a software delay loop that counts the variable (unsigned int counter) from 0 up to 40,000 to create a small delay. If the user wishes to double the delay, can they simply increase the upperbound to 80,000?
b. If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Answer:
Explanation:
The objective here is to determine if the programmer can simply increase the upperbound to 80,000.
Of course Yes, The programmer can simply increase the delay by doubling the upperbound by 80000. The representation can be illustrated as:
( int : i = 0; i < 40,000; i ++ )
{
// delay code
}
Which can be modified as:
( int : i = 0; i < 80,000; i ++ )
{
// delay code
}
b) If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Assuming there is no delay being created at the run-time,
The code is illustrated as:
For ( int : i = 0 ; i < 0 ; i ++ )
{
// delay code which wont
//execute since code delay is zero
}
we ought to check whether the loop is being satisfied or not. At the Initial value of loop variable, is there any break or exit statement is being executed in between loop. Thus, the aforementioned delay loop wont be executed since the loop wont be executed for any value of i.

Account Balance Design a hierarchy chart or flowchart for a program that calculates the current balance in a savings account. The program must ask the user for:________.
A- The starting balance
B- The total dollar amount of deposits made
C- The total dollar amount of withdrawals made
D- The monthly interest rate
Once the program calculates the current balance, it should be displayed on the screen.
Answer:
a. starting balance
Explanation:
A program that calculates the current balance of a savings should ask the user for the starting balance and then ask for the annual interest rate. A loop should then iterate once for every month of the savings period in order to perform other tasks such as asking the user for the total amount deposited into the account, the total amount withdrawn from the account, and calculate the interest rate. The program will then proceed to display the result at the end of the savings period.
C++ Problem: In the bin packing problem, items of different weights (or sizes) must be packed into a finite number of bins each with the capacity C in a way that minimizes the number of bins used. The decision version of the bin packing problem (deciding if objects will fit into <= k bins) is NPcomplete. There is no known polynomial time algorithm to solve the optimization version of the bin packing problem. In this homework you will be examining three greedy approximation algorithms to solve the bin packing problem.
- First-Fit: Put each item as you come to it into the first (earliest opened) bin into which it fits. If there is no available bin then open a new bin.
- First-Fit-Decreasing: First sort the items in decreasing order by size, then use First-Fit on the resulting list.
- Best Fit: Place the items in the order in which they arrive. Place the next item into the bin which will leave the least room left over after the item is placed in the bin. If it does not fit in any bin, start a new bin.
Implement the algorithms in C++. Your program named bins.cpp should read in a text file named bin.txt with multiple test cases as explained below and output to the terminal the number of bins each algorithm calculated for each test case. Example bin.txt: The first line is the number of test cases, followed by the capacity of bins for that test case, the number of items and then the weight of each item. You can assume that the weight of an item does not exceed the capacity of a bin for that problem.

Write a function called unzip that takes as parameter a sequence (list or tuple) called seq of tuples with two elements. The function must return a tuple where the first element is a list with the first members of the seq tuple and the second element is a list with the second members of the seq tuple.
This example clarifies what is required:
Ist =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(Lst) lst tup
print(tup)
#prints ([1, 2, 3], ['one', two','three'7)
Answer:
Here is the function unzip:
def unzip(lst):
result= zip(*lst)
return list(result)
The complete program in Python is given below:
def unzip(lst):
result= zip(*lst)
return list(result)
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
Explanation:
Here zip() function is used in the unzip function. The return type of zip() function is a zip object. This means the function returns the iterator of tuples. This function can be used as its own inverse by using the * operator.
If you do not want to use zip() function then the above program can also be implemented as following which uses a for loop for elements in the given list (lst). This can make a pair of lists (2 tuple) instead of list of tuples:
def unzip(lst):
output = ([ a for a,b in lst ], [ b for a,b in lst ])
return output
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
The programs along with their output are attached.

Explanation:
If a large organization wants to develop a software that will benefit the entire organization such software will be known as an enterprise application software and such application software must be developed in such a way that it meets the required purpose for which the organization is designed it for.
An enterprise application software is a computer software developed specially to satisfy the specific needs of an entire organization inside of the individual needs of the people working in the organization.
Write a program in C# : Pig Latin is a nonsense language. To create a word in pig Latin, you remove the first letter and then add the first letter and "ay" at the end of the word. For example, "dog" becomes "ogday" and "cat" becomes "atcay". Write a GUI program named PigLatinGUI that allows the user to enter a word and displays the pig Latin version.
Answer:
The csharp program is as follows.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string word = textBox1.Text;
string ch = word.Substring(0, 1);
string str = word.Substring(1, word.Length-1);
string s = str.Insert(str.Length, ch);
textBox2.Text = s.Insert(s.Length, "ay");
}
private void button3_Click(object sender, EventArgs e)
{
Close();
}
private void button2_Click(object sender, EventArgs e)
{
textBox1.Text = "";
textBox2.Text = "";
}
}
}
Explanation:
1. A string variable to hold the user input is declared and initialized accordingly. The user inputted string is taken from textbox1.
string word = textBox1.Text;
2. A string variable to hold the first character of the user inputted string is declared and initialized.
string ch = word.Substring(0, 1);
3. A string variable to hold the user inputted string without the first character is declared and initialized accordingly.
string str = word.Substring(1, word.Length-1);
4. A string variable to hold the substring from step 3 along with the inserted characters at the end, is declared and initialized accordingly.
string s = str.Insert(str.Length, ch);
5. The final string is assigned to the textbox 2, which is the PigLatin conversion of the user inputted string.
textBox2.Text = s.Insert(s.Length, "ay");
6. All the above take place when the user clicks Convert to PigLatin button.
7. Two additional buttons, clear and exit are also included in the form.
8. When the user clicks clear button, both the textboxes are initialized to empty string thus clearing both the textboxes.
textBox1.Text = "";
textBox2.Text = "";
9. When the user clicks the exit button, the application closes using the Close() method.
10. The program is done in Visual Studio.
11. The output of the program is attached.
12. The program can be tested for any type of string and any length of the string.
During an investigation of a cybercrime, the law enforcement officers came across a computer that had the hard drive encrypted. Chose the best course of action they should take to access the data on that drive.
a. Use image filtering techniques to see what's behing the encrypted files.
b. Try to convince the owner of the computer to give you to decryption key/password.
c. Identify the encryption algorithm and attempt a brute force attack to get access to the file.
d. Disconnect the hard drive from power so the encryption key can be exposed on the next power up.
e. Try to copy the drive bit by bit so you can see the files in each directory.
Answer:
b. Try to convince the owner of the computer to give you to decryption key/password.
Explanation:
Encrypted hard drives have maximum security and high data protection. to access them you need to enter a password to unlock them.
The image filtering technique is a method that serves to selectively highlight information contained in an image, for which it does not work.
The encryption algorithm is a component used for the security of electronic data transport, not to access data on an encrypted hard drive.
The encryption key is used in encryption algorithms to transform a message and cannot be exposed by disconnecting the hard drive from its power source.
2) An algorithm that takes in as input an array with n rows and m columns has a run time of O(nlgm). The algorithm takes 173 ms to run in an input array with 1000 rows and 512 columns. How long will the algorithm take to run on an input array with 1500 rows and 4096 columns? (Note: For ease of calculation, please use a base of 2 for your logarithm.)
Answer:
The algorithm takes 346 ms to run on an input array with 1500 rows and 4096 columns.
Explanation:
For an input array with 1000 rows and 512 columns, the algorithm takes 173 ms.
We want to find out how long will the algorithm take to run on an input array with 1500 rows and 4096 columns?
Let the algorithm take x ms to run 1500 rows and 4096 columns.
For an input of n rows and m columns, it takes
[tex]n \: log_{2} \:m[/tex]
So,
[tex]1000 \: log_{2} \:512 = 173 \\\\1000 \: log_{2} \:2^{9} = 173 \:\:\: ( 2^{9} = 512) \\\\1000 \times 9 = 173 \:\:\:\:\: \: \: eg. 1[/tex]
and
[tex]1500 \: log_{2} \:4096 = x \\\\1500 \: log_{2} \:2^{12} = x \:\:\: ( 2^{12} = 4096) \\\\1500 \times 12 = x \:\:\:\:\: \: \: eg. 2[/tex]
Now divide the eq. 2 by eq. 1 to find the value of x
[tex]\frac{1500 \times 12}{1000 \times 9} = \frac{x}{173} \\\\\frac{18000 }{9000} = \frac{x}{173} \\\\2 = \frac{x}{173} \\\\x = 2 \times 173 \\\\x = 346 \: ms[/tex]
Therefore, the algorithm takes 346 ms to run on an input array with 1500 rows and 4096 columns.
